More Words by Henry Dreyfuss

[HobieSport]

"How easily we take for granted that the simple, commonplace spinning of a dial will enable us to talk privately and intimately with a particular person across a city or continent or an ocean or on a speeding train or a ship at sea or in an auto or in a plane several miles in the sky."

Henry Dreyfuss
Designing for People
Chapter Seven
Sentence Two

I like that sentence because Henry was conservative and modest in Industrial Design but it shows his enthusiasm for the 500.
